摘      要：Background and Objectives The relationship between left atrial(LA)size and congestive heart failure(CHF)is well recognized;however,there is little information on the association of pulmonary vein(PV)diameter and *** purpose of this study was to investigate the changes of PV and LA sizes in CHF patients by multislice computed tomography(MSCT)angiography using a new 64-slice *** and Results We assessed diameters of PVs ostium and LA by 64-slice MSCT with three-dimensional reconstruction in 25 CHF patients and in 26 age-and sex-matched non-CHF *** with controls,CHF patients showed significant greater diameters of left superior pulmonary vein(LSPV)and right inferior pulmonary vein(RIPV)in both anteriorposterior(AP)and superior-inferior(SI)directions(P0.01),significant dilation of right superior pulmonary vein(RSPV)in AP direction(P0.05),as well as significant increase of LA transverse,AP,and SI diameters(P0.01).Conclusion Significant dilation of PVs with simultaneous LA enlargement was demonstrated in CHF *** anatomic and geometric changes may participate in the perpetuation of AF.
